While there is limited sheep corn stalk grazing research data available if one extrapolates Iowa State University beef cow data it would appear that corn stalk residue can easily provide 150 to 300 ewe grazing days per acre. If ewes have been boostered annually against enterotoxemia (overeating) before lambing, this management input can be skipped prior to going to stalks.

Vaccination against enterotoxemia (“overeating disease”) with a subcutaneous injection of Clostridium perfringens type-D toxoid 4 to 6 weeks prior to entering stalk fields offers low cost added protection for the flock. Offering ewes a small amount (~0.5 lb.) of corn for three to seven days before grazing will also help to minimize problems with grain. When ewes are initially turned into stalk fields they should have restricted daily access of one to two hours on stalks. Acidosis resulting from grain overload can be minimized by gradually introducing ewes to corn stalk fields. The major concern with introducing ewes to harvested corn fields is grain overload with rumen acidosis and overeating disease. you have enough sheep to fully utilize crop residue.weathering causes minimal deterioration of quality.(Previously published with MSU College of Veterinary Medicine – Sheep publication: December 10, 2008)Įwes can utilize corn stalks for most, if not all of their daily nutrients if:

Joseph Rook, Extension and Agriculture Experiment Station, Michigan State University Research data from SDSU suggests that replacement heifers that spend at least some time grazing post-weaning adapt better to grazing later in their life compared to heifers that are strictly developed in the drylot.Dan Morrical, Extension Sheep Specialist, Iowa State University High rates of gains aren’t required in those systems keeping winter feed expenses to a minimum plays a greater role in profitability. This system is well suited for winter-feeding calves that are intended to go to grass next summer and for developing replacement heifers. Increased stocking rates would tend to depress performance compared to lower stocking rates. Because residue digestibility declines with time, stocking a field of 160 bushel production with two calves per acre should provide enough residue for 50 days. That would be enough forage for 100 days for a 550 pound calf. The estimated utilization rate is 50% because of trampling loss and other disappearance, resulting in about 1200 pounds of consumed residue. There’s approximately 15 pounds of husks and leaves for every bushel or corn, so if a field yields 160 bushels per acre that would mean there would be about 2400 pounds of husks and leaves available. How many calves can be grazed on an acre of corn stalks? The supply or residue varies with the grain yield. Supplements should be selected on the basis of cost per unit of delivered nutrients. shows replacement heifers being developed in NE South Dakota on corn stalks while being supplemented with 7 pounds of alfalfa per head per day. Other high-protein feeds could be used as well.

Free choice mineral containing salt, additional calcium, trace minerals, and Vitamin A should be provided free choice.

Because DDGS are relatively high in phosphorus, no additional phosphorus would need to be provided in this situation. Calves have gained between 1.5 and 2.0 pounds per day when supplemented with 3-6 pounds of DDGS. Distillers grains work well as a supplemental feed for calves grazing corn stalks.
